PROCESS OF MAKING ARTIFICIAL FUEL.

srriGlFIGATION forming part of Letters Patent No. 729,711, dated June 2,1903.

Be it known that I, GEORGES ADROT, acit izen of the French Republic, anda resident of Marseilles, France, have invented certain new and usefulImprovements in Processes of Making Artificial Fuel, of which thefollowing is a specification.

The object of the invention is to provide a solid fuelconlainingpetroleum which shall be easily manufactured and which shall beexceedingly eifective and economical.

According to my invention I incorporate or mix petroleum with sodiumresinate. I then add some combustible or carbonaceous mat-- ter-such,for instance, as pulverized coal, sawdust,leaves,or grassand the pasteWhich results is diluted with hot water containing in solution asuitable metallic salt which gives an insoluble resinate. I prefercaustic lime or salts of lime, such as chlorid of calcium. This mixtureloses its water very rapidly and has when cool a solid appearance, whileit is sufliciently elastic to allow it to be pressed into any desiredshape by any suitable machinery. The resulting blocks are as combustibleas are the ordinary fuels and leave no appreciable amount of ashes.

In case petroleums are used containing very volatile ingredients it isnecessary to heat the blocks or briquets to a quite high temperature-say100to allow the volatilization of the light oils.

Having thus described my invention, what I claim is The herein-describedprocess of making artificial fuel which consists in incorporatingGEORGES ADR OT.
